[Euro] Shape of fuel tank?

[BiLL|z0r]

I'm wondering if any1 has a cross section of the Euro's fuel tank. Is it just square or oddly shaped? The reason I ask is fuel consumption. When I first fill up the needle hardly moves for the first 100km's or so, then it seems to go from just under full to just over half for the next 100km's, then it slows again and only drops a couple marks for the next 100kms, then quickly till about 1/4, then slow, then whack on E before you realise.
I do 95% city driving so it's not highway driving causing better fuel economy so I put it down to the shape of the tank.

That's some bad fuel consumption even for city driving unless you drive around only in rush hour traffic.

In worst case scenario, my needle doesn't move at all until around 50km. down to 3/4 mark at about 150km. 1/2 way mark around 250-300km, 1/4 mark around 400-450km and around 550km when the warning light is about to come on

[aaronng]

It could the fuel level indicator/detector. On mine, it is 100km till the needle starts to hit the first bar, and then 100km for each quarter on the gauge (very consistent!), and when the light comes on, I have about 80-100km left (for my driving style).

Most of my driving is stop/go (too many traffic lights on the Gold Coast) + I have an auto. I get about 450km's to the tank on average. Worst has been 390km's, best has been 550km's for city driving (that was on optimax extreme). On the highway I can easily make over 750km's.

I do have a bit of a lead foot, but latelly I have been driving better on purpose to get better fuel economy, however I do notice the same fuel usage pattern.

According to the book, you should have a 65L fuel tank. Based on the fuel consumption figures qutoed by honda (if you believe them?) it should use ~10.8L/100kms for a honda euro lux auto [combined city+hwy].

doing the cal you should get 602kms per tank! this includes the period when the warning light turns on. i remember reading in the book that you have another 10L of fuel when it turns on. this means you sould be able to get ~500kms before light comes on

what you will find is these figures a calculated based on the A/C turned OFF !!
considering you live on the gold coast, this will be the reason for your high fuel use.
the car uses more fuel to run the air-conditioning. start and stop driving or agressive driving will also contribute to this.

try leaving the a/c off and notice the diff, i have!

I think I'll leave that experiment till it's a lil cooler :) For the time being I'll drive a lil less "excited". :D I'm sure my license will love me as well if I do.

I am getting the same responses as Aaronng, all very consistent. About 100 kms plus available when the fuel indicator light comes on. The fuel gauge will remain static for some time IF you have overidden cut-off at the bowser. All this means is that their is excess fuel laying in the re-fuelling pipe. I think I remember reading somewhere in the Owners Manual not to fill past the 3rd click at the bowser as this may incur problems? For consistency in checking fuel consumption I close off at the first click. I am averaging exactly 7.98Litres per 100kms since June 05

^^ yeah, there is a sensor where if you don't tighten your fuel cap properly, your check engine light comes on. I think if you fill it too high, then the sensor goes off even though the cap is on properly.

hey coladuna... do you have any mods on ur car to get those figures?

i just bought my euro recently and i'm not sure if it has to do with driving around mainly around the suburbs but the best i can get is 420km from a tank of fuel

i've heard that havin 18' rims increase consumption

considering thats the only mod i have that'll affect fuel consumption, i didnt think that it would that much of an impact :confused:

That's about right for start stop driving with the 5AT. Coladuna's using the 6MT, and I too get the same 550km before the light comes on.

Most of fuel tanks nowaday are odd shape to fill up the space between rear seat and spare wheel. In the good old days, they used to be situated bottom of the trunk, but due to safety issue, they are moved forward to minimise the risk of bursting tank after car crash.

Toyota's fuel gauge also possess the same characteristic as Euro: ie, dropping rather fast at bottom half of the tank.

Freqqie, for your info, with 6MTEuro, 550km /tank (when warning light on) is quite normal.. My 2003 6MT consistantly get 12.7km/L with 16", about 11.7/L with 18" There is also another very comprehensive thread discussing Euro's Fuel comsumption..

No, I don't have a single mod on my car. My fuel consumption never ever went above 9.5L/100km since I owned the car back in Sept 2004.
On a trip to Sunshine Coast from Brisbane, I managed around 7.8L/100km with 4 adults and luggage in the boot with air conditioning turned on the whole time.
I think the fuel light came on when I did almost 700km, which was impressive.

Funny you meantion that, my engine light was on for a bit a few days ago and now you meantion it, I think it was right after refueling. I do usually go 2-3 clicks of the pump.

i get about 580km per tank every time i fill up
when i fill up all the way, the needle goes past the F and the bar that F is on.
when i reach my first 100kms or so, it drops to the F and that bar.
200kms, about 1/4 of the way down
300kms, almost hitting the halfway mark....i hit halfway at about 350-60kms.
then 400kms goes to just above 1/4 tank left.....
450kms, just under 1/4
500kms the needle is going towards moer to the E now
550kms, just a few mm from the E point
560kms or thereabouts is when my needle is right next to the E
570kms my fuel light comes on

this is with city driving travelling at about 60-90kms on normal roads, start stop and travelling on the highway (usually M2 and M7).
mods done to my car that would affect fuel consumption are my 20's and CAI. other than that, nothing else. Oh and i never have the A/C on either.

Mmmm just wondering for Auto trans. users, when you are at red light (already stationary) - do you put your gear to N to conserve fuel?? is it effective? or just a myth?

Does it wear the gearbox off by doing that? is it worth it?

My friend told me that when stationary if you keep on braking, you actually wasting fuel so better to use hand brake and put the gear in N.

:confused:

[ROBERT]

Having learned to drive in England it was (still is?) recommended to put the gearbox in neutral (either auto or manual) whilst stationary and put the hand brake on. This is for safety reasons mainly, but with an auto the engine is trying to drive but being held back by the brake, so logic says it has to use more fuel. In the case of a manual then holding the clutch in whilst stationary is just wearing the thrust bearing away.

[Adagio]

One of my pet hates is to see drivers sitting at the lights with the foot brake applied and probably in gear. As "Robert" states it wears the thrust bearing on manual cars and just wastes fuel anyway. Of more importance what happens in these situations if someone gets nudged/bumped from behind? You guessed it, off goes the foot brake and all hell can break loose, especially if the wheels are turned as this will cause the car possibly to cross oncoming traffic. Far better all round to sit with the handbrake on, in neutral and your wheels pointing straight ahead.

Okay... thanks for the quick reply :)

I was taught by my instructor years ago that changing from D to N on an auto gearbox at the stop lights actually wears out the gearbox faster than if you let it sit on D and press on the brake pedal. I know however, as I learnt on a manual car, that I was taught to put the gear into neutral and to either press on the brake pedal, or to pull the handbrake if the stop will take a while/car is slightly inclined upwards.

maybe he's wrong, seeing how instructors don't generally preach the same consistent message at times. :(

[Adagio]

Your driving instructor may have been right about the wear, I don't know on that score BUT you are much safer to yourself and everyone else if you car is in Neutral or Park and the hand brake on.
